AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
1052 AM EDT FRI JUN 8 2007

.UPDATE...CONVECTION FIRING ALONG FINE LINE/COLD FRONT...JUST WEST
AND NORTH OF APX PROPER. WILL INCREASE POPS AND ADD THUNDER EARLY
TODAY EAST OF THE FRONT.

COLD FRONT MOVING INTO THE FORECAST AREA THIS MORNING...
CURRENTLY JUST THRU THE SAULT AND MANISTEE. LINGERING LOW LEVEL
MOISTURE (SURFACE DEW POINTS STILL LOW-MID 60S) HAS PRODUCED A FAIR
AMOUNT OF MVFR STRATOCU ALONG/AHEAD OF THE FRONT. THERE IS A SMALL
AREA OF CLEARING IMMEDIATELY BEHIND THE FRONT...THEN MORE STRATOCU
AND EVEN A FEW SPRINKLES BACK IN WI/CENTRAL UPPER MI.

WILL GO WITH ISOLATED SHOWERS IN THE POST-FRONTAL MOISTURE BAND...
AND FINE TUNE THE ARRIVAL AND DEPARTURE OF PRECIP IN THE GRIDDED
FORECAST (MAINLY TO SLOW THINGS DOWN A BIT). OTHERWISE...A PARTLY TO
MOSTLY CLOUDY DAY IS ON TAP...WITH CLEARING FROM WEST TO EAST VERY
LATE. TEMPS WILL FALL THRU THE 60S BEHIND THE COLD FRONT.

ZOLTOWSKI

&&

.AVIATION...VFR CONDITIONS PRIMARILY EXPECTED THROUGH THE TAF
PERIOD. COLD FRONT WILL MOVE THROUGH THE AREA THIS MORNING...BUT
WITH LITTLE IN THE WAY OF ADDITIONAL PRECIPITATION. WITH COOL AIR
MOVING IN ALOFT...EXPECT CU/STRATOCU WILL DEVELOP THIS
AFTERNOON...WITH THE POSSIBILITY FOR BRIEF PERIODS OF MVFR
CEILINGS...THOUGH MOSTLY VFR. COULD ALSO SEE A FEW SHOWERS AS UPPER
TROUGH AXIS SWINGS THROUGH THE AREA...BUT CONFIDENCE LOW ENOUGH TO
PRECLUDE ANY MENTION AT THIS POINT. WINDS WILL REMAIN GUSTY
INITIALLY FROM THE SOUTHWEST...THEN SHIFTING WEST BY EARLY
AFTERNOON...WITH GUSTS OF 25 KNOTS EXPECTED THROUGH LATE AFTERNOON.
CLOUDS WILL BE ON THE WANE QUICKLY BY SUNSET AS HIGH PRESSURE BUILDS
INTO THE REGION...WITH WINDS DIMINISHING AS WELL...GENERALLY UNDER 5
KNOTS FOR THE OVERNIGHT.

.PREV DISCUSSION... /ISSUED 417 AM EDT FRI JUN 8 2007/

DISCUSSION...ACTIVE WEATHER ONGOING ACROSS THE CWA EARLY THIS
MORNING IN ADVANCE OF IMPRESSIVE SHORTWAVE PROGRESSING THROUGH THE
UPPER MIDWEST. IMPRESSIVE DEEP LAYER WIND FIELDS (0-6KM SHEAR OF 60
KNOTS OR BETTER) COUPLED WITH INFLUX OF MID LEVEL DRYING AIDING IN
PRODUCING LONG LIVED BOWING FEATURE OVER THE SOUTHERN CWA.
INSTABILITY ALSO IMPRESSIVE WITH MLCAPES STILL RUNNING AROUND 1000
J/KG GIVEN TEMPS STILL IN THE 70S AND DEW POINTS WELL INTO THE 60S.
DESPITE THE ROCKY START TO THE DAY...CHANGES ARE IN STORE BY LATE
AFTERNOON...CONTINUING THROUGH THE WEEKEND AND INTO NEXT WEEK AS
HIGH PRESSURE TAKES UP RESIDENCE ACROSS THE REGION. THUS...THE
BIGGEST FORECAST CONCERN FOR THE NEXT FIVE DAYS IS TEMPERATURES.

EXISTING LINE OF SHOWERS AND STORMS WILL EXIT STAGE RIGHT EARLY THIS
MORNING AS UPPER WAVE PUSHES INTO THE WESTERN LAKES AND ASSOCIATED
COLD FRONT CROSSES THE REGION BETWEEN 12Z AND 16Z. RESIDUAL FORCING
PER 700-500 MB QG CONVERGENCE ASSOCIATED WITH THE APPROACH OF THE
WAVE AND RESIDUAL MOISTURE MANDATES A CONTINUED MENTION OF SCATTERED
SHOWERS HEADING INTO THE AFTERNOON. HOWEVER...THINGS LOOK TO DRY OUT
QUICKLY FROM WEST TO EAST BY LATE AFTERNOON AS MUCH DRIER AIR AND
SUBSIDENCE OVERSPREAD THE AREA WITH PASSAGE OF THE UPPER WAVE. A
TOUGH CALL AS TO WHETHER ADDITIONAL CONVECTION MAY FIRE OVER THE FAR
SOUTHEAST CWA WHERE FRONT WILL BE LAST TO PASS...AND SOME POTENTIAL
FOR QUICK HEATING (GIVEN TEMPS ALREADY SO WARM) TO ALLOW FURTHER
DESTABILIZATION. BUT GIVEN EXPECTED CONVECTION EARLY THIS
MORNING...THINK THINGS MAY BE SUFFICIENTLY WORKED OVER...AND FRONTAL
PASSAGE TOO EARLY...TO ALLOW FOR ADDITIONAL CONVECTION IN THE APX
CWA. SHOULD SEE CLOUDS LINGER FOR A WHILE GIVEN UPSTREAM LOW DECK
ALONG AND JUST BEHIND THE ACTUAL FRONTAL PASSAGE...AS WELL AS
ADDITIONAL EXPECTED CU/STRATOCU DEVELOPMENT AS COLD POOL OVERTAKES
NORTHERN MICHIGAN BY AFTERNOON. THIS WILL MAKE FOR A TRICKY HIGH
TEMP FORECAST...AS HIGHS LIKELY TO COME THIS MORNING FOR MOST
SPOTS...WITH TEMPS FALLING BY LATE MORNING INTO THE AFTERNOON WITH
ONSET OF STRONG PUSH OF COLD ADVECTION. H85 TEMPS PROGGED TO CRASH
FROM 15-17C DOWN TO ONLY 4-5C PER UPSTREAM RAOBS INDICATIVE OF TEMPS
LIKELY DROPPING INTO THE 50S...WITH WINDS CONTINUING TO REMAIN GUSTY
THROUGH THE DAY AS GRADIENT REMAINS TIGHT.

SMOOTH SAILING THEN EXPECTED STARTING TONIGHT...AND CONTINUING
THROUGH THE WEEKEND. LOW LEVEL RIDGING WILL TAKE HOLD IN THE WAKE OF
DEPARTING SHORT TERM LOW PRESSURE...AS FLOW ALOFT BECOMES MORE
ZONAL. LIGHT SYNOPTIC FLOW ENVIRONMENT WITH H95-H9 WINDS ONLY ABOUT
10 TO 15 KNOTS WILL BE SUPPORTIVE OF DAILY LAKE BREEZES...KEEPING
TEMPS COOLER ALONG THE LAKESHORE. OTHERWISE...SLOW RECOVERY OF
AIRMASS AS RIDGE AXIS DRIFTS EAST OF THE AREA COUPLED WITH PLENTIFUL
INSOLATION GIVEN LACK OF BOUNDARY LAYER MOISTURE TO DRIVE AFTERNOON
CU AND DEEP LAYER SUBSIDENCE WILL EASILY SUPPORT HIGHS NEAR
NORMAL...GENERALLY IN THE LOWER TO MIDDLE 70S.

SIMILAR WEATHER PATTERN WILL PERSIST INTO EARLY NEXT WEEK...WITH
BUILDING HEIGHTS AS MID LEVEL RIDGE AMPLIFIES ACROSS THE REGION.
ONLY CHANGE WILL BE A RETURN TO SLIGHT MORE MILD/HUMID CONDITIONS AS
LOW LEVEL FLOW TURNS MORE SOUTHWESTERLY IN RESPONSE TO EASTWARD
DISPLACEMENT OF LOW LEVEL RIDGE AXIS AS NEXT SYSTEM UPSTREAM DIGS
INTO THE CENTRAL ROCKIES. DAILY LAKE BREEZES WILL ONCE AGAIN BE THE
RULE WITH CONTINUED LIGHT SYNOPTIC FLOW AND GOOD HEATING. ADDED
BOUNDARY LAYER MOISTURE COUPLED WITH LOCAL CONVERGENCE LOOKS LIKE IT
MAY PROVE SUFFICIENT TO POP A FEW SHOWERS MONDAY AFTERNOON WITH
SBCAPES PROGGED AROUND 400 J/KG...WITH SIMILAR CONDITIONS POSSIBLE
ON TUESDAY...THOUGH INCREASED MID LEVEL SUBSIDENCE INVERSION/CAPPING
APPEARS ENOUGH TO PRECLUDE ANY MENTION AT THIS TIME.

MARINE ISSUES...WILL CONTINUE SMALL CRAFTS FOR ALL AREAS THROUGH 18Z
TODAY GIVEN INITIALLY STRONG GRADIENT SLOW TO RELAX UNTIL LATE
AFTERNOON AS LOW PRESSURE DEPARTS INTO EASTERN CANADA. STRONGEST
WINDS EARLY THIS MORNING WILL REMAIN ALONG THE LAKE MICHIGAN
SHORELINE OF NORTHERN LOWER WHERE COASTAL CONVERGENCE EFFECTS WILL
COME INTO PLAY. BY AFTERNOON...AS FLOW BECOMES MORE
WESTERLY...EXPECT THE STRONGEST WINDS TO OCCUR ACROSS THE STRAITS
WHERE CHANNELING WILL AID IN BOOSTING SPEEDS.
